CONDENSI-NG rLuInsUBs'rANcEs.

To all whom it may concerni- Be it known that I, ALBERT G. KALB, a

citizen of the United States of Americafand resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Condensing Fluid Substances, of which the following is a specification.

This invention relates toimproveinents in method of condensing fluid substances and the invention is adapted more particularly for condensing milk.

The ob ect of my invention is to invent a simple method which will make it possible to condense milk by an economical process and without the use of undue heat.

Inthe preferred form of apparatus for carrying out my method, the material to becondensed is contained in a suitable tank which may be heated as by a water or steam jacket and with this tank I employ a spraying chamber in which the material to be condensed is introduced in the form of a fine spray and at the same time subjected to a constantly maintained current of dry warm air, the said air being replenished in great,

1 volume and acts upon the sprayed milk to take up the liquid particles of the-same and the air is then forced through the body of the milk and out of the tank in any desirable way.

broadly speaking, as justdescribed and as hereinafter claimed.

In the drawings accompanying and forming part hereof Figure 1 is a View, part in side elevation but mostly in vertical section,

of apparatus constructed to carry out my method. Fig. 2 is a horizontal section through the line 2, 20f Fig; 1. ;-Fig. 3 is a horizontal section through the line 3, 3 of Fig. 1. k v V Referring now to the details of the draw-. ings by numerals: 1 designates a tank which-- may be open at the top as illustrated andwhich is provided with a heating jacket 4 .to

which a heating mediurnmay be supplied through the pipe 5 shown in Fig. -1. The

tank also is provided with a supply pipe fl,

an overflow 8, and a' discharge pipe 9..

Within the tank is a spraying chamber formed of two telescopic members 12 and 14c,

the member 12 being adjustably supported by the member 1 1 by means of wing nuts 15 so that the member 12 may be lowered withconsists of a method,

V I I i in the tank 1 as may be necessary inorder I. to insure that the lower end of said tank," shall always be submerged in the -material to be condensed and to make it possibleto lowers in the operation of condensing the lower said member-12 as the fluid substance same; The member 14 is provided with ,an

inlet pipe 17 of large area which'is connected f with a blower 18 which exhausts air from a The lower adjustable member 12 of the spraying chamber is'provided with perform tions 13 through which the material tdbe condensed passes and finds the same levelwithin the. spraying tank'as'itdoes in the The spraying chamber is also provided with a series of spraying devices or atomizers 24 supplied by a pipe- 26 connected with a pump 28 and this pump condensing tank 1.

connects with the bottom of the tank 1 by means of the pipe 29 andby the action of the pump 28 the material being condensed "is drawn from the tankl, forced-through the pipe 26 through the spraying devices 24-, where it subjected to. the action of large volumes of constantly sup-plied heated and dried air introduced intothe spraying chamaction of the heating" her by means of the aforesaid blower 18. .7

.Within the bottom of the tank 1 is also provided an agitator 29 operated from a pulley 30 and this agitator 29 is adapted to'create a slight current in the liquid to be condensed by'fdrawing said material down one side of; thechamber and permitting 1t to flow, up.

the other side,- thus keeping the material of uniform conslstency, and preventing the for- *mat-ion of foam. 7 v

The operation of my invention is as fol-' lows By means of the blower 18, air in large volumes is drawn through the in let 22 and heated and dried by heater 21 and forced through theinlet-1-7 into the-spraying cham-' her. In ordery to find exit from this, spraying chamber the air must 'pass 'clown' through the. perforations 13 inflthe'yl'ower member 12 of said tank andpass through'the material to be condensed-where it-may escape freely through the open top of the tank 1 but in doing this the largei'volume of air introduced into the spraying chamber comes in contact with the sprayed or atomized particles from the spraying devices 5 24: and of course tends to absorb to a large extent the liquid from said particles, thereby carrying off the moisture from these atomized particles and gradually condensing the ma terial to any extent desired. As the material is condensed, the adjustable member l2 may be lowered to keep its perforated end surrounded by the material being condensed and when said material is condensed to the desired consistency it may be delivered through the discharge pipe 9, and a new supply of liquid subjected tion process. I

From the foregoing and the accompanying drawings, it will be seen that I have invented to the condensaa method of condensing fluid substances in the apparatus for carrying out my method Without departing from the spirit thereof,-

the scope of the invention being set forth by the appended claims.

The apparatus illustrated and described is not herein claimed, but forms'the subject matter of a separate application, filed July 30, 1908, Serial Number 446,169.

What I claim as my invention is:

1. The method of condensing fluid substances which consists in introducing the material in atomized condition to a current of air, maintaining the air in motion, and forcing the air through the body of mate-v rial being treated, substantially as described.

2. The method of condensing fluid substances which consists in subjecting air to a spray of liquid material and in forcing the air so sprayed through .the material being treated, substantially as described.

3. The method of condensing fluid substances which consists in subjecting air to a spray of liquid material, in forcing the air so sprayed through "the material, and in keeping the liquid in motion, substantially as described. v I
